Answer:
131
Step-by-step explanation:
Using proportion,
If Out of 550 calculators = 6 are defective,
Then out of 12000 calculators = ? are defective
= 21.8 * 6
= 130.8 ≈ 131
∴ Approximately 131 calculators are defective
jerome measures the length of 40 ropes and uses a line plot to organize his data. how many more ropes are there that are 3/8 yar
1 answer:
There are 15 ropes 3/8 yard long or greater than ropes that are less than 3/8 yard long
<h3>What is a line plot?</h3>A Line plot (dot plots) is a graph or plot that displays on a number line, showing the frequency of each value.
From the image showing the line plot below:
Number of ropes 3/8 yard long or greater than ropes that are less than 3/8 yard long = 5 + 4 + 6 = 15
There are 15 ropes 3/8 yard long or greater than ropes that are less than 3/8 yard long

Formula for the volume of cone is
Where r= radius of the cone
h = height of the cone
The value of pi is 3.14
Given volume of larger cone is 131 cm^3
Volume of larger cone =
131 =
Solve for h
131 = 26.1667 *h
So h= 5 cm
The height of bigger cone = 5cm
Now we find the volume of smaller cone
Two cones similar so the sides are in proportional
Height of smaller cone = 2cm
volume of smaller cone =
= 8.38cm^3
